400 Piper : Noteworthy Northwestern Plants 



6-j mm. long, including the style : style 1.5 mm. long: stigmas 



thick, glandular, broad, entire or two-lobed or cleft ; pedicel 1-2 

 mm. long : nectary small, one half as long as the pedicel : stami- 

 nate aments 1—2 cm. long, densely flowered ; scales black, ovate, 

 usually acute, persistent, 2 mm. long, densely villous with long 

 tawny hairs : stamens 2, usually unequal, twice as long as the 

 scale : filaments free : anthers yellow : nectary small, about one 

 fourth as long as the scale. 



First detected near Garrison, Whitman Co., Wash., by Prof. 

 L. F. Henderson. In this place only a dozen or more plants 

 occur, but the species is abundant along the north fork of the 

 Palouse between Colfax and Palouse, Wash., and along the 

 Potlatch River near Collins, Idaho ; also at Jansville, Idaho. 



This species is one of the obscure Salix pellita group and ap- 

 parently the only one of which complete material has been col- 

 lected. Its relationship is with S. Candida. 



From 5. pellita and at least so far as the Lyall type specimen 

 is concerned, 5. bella differs in these important particulars : the 

 pistillate aments are sessile or nearly so ; the capsule is smaller 

 and more sericeous ; the scale is black, obtuse, long villous instead 

 of brown, acute, and sparsely pilose ; and the stipules are well 

 developed. The leaves too are quite different. 



Salix subcoerulea sp. nov. 



111 ' - 



Shrub about 2 meters high : branchlets dark, glabrous, bluish 

 with a bloom that easily rubs off: leaves oblong-lanceolate, oc- 

 casionally oblanceolate, acuminate, acute at base, entire or ob- 

 scurely crenulate, above green and minutely pubescent, beneath 

 silvery appressed pubescent but scarcely tomentose, 2—5 cm. long, 

 1 cm. wide ; pedicels short, about .5 cm. long : stipules obsolete : 

 pistillate aments appearing with the leaves, pedunculate, usually 

 with one or more small leaves at base, 2.5-4 cm. long, less 

 than 1 cm. thick, erect, straight or cernuous : capsules short- 

 pedicelled, pyriform, silvery sericeous, 2-3 mm. long, tipped 

 with a slender yellow style 1 mm. long : stigmas thick, usually 

 2-lobed : scales black, ovate, obtuse, about 1 mm. long, sparsely 

 pilose, with white hairs of the same length : pedicel about 1 mm. 

 long, twice as long as the nectary : staminate aments unknown. 



Oregon : Powder River Mts., in wet meadows near the head 

 of Eagle Creek, Cusick, no. 1302, Piper, no. 2533 : also near the 

 head of Anthony Creek, Cusick.
